CATEGORY Pot Bearings
VERSION EN-1.0
[POT] POT Bearings Product Description High performance mechanical bearing allowing high vertical and horizontal loads.
Bearings are constituted of 3 main steel elements: Pot [1], Piston [2] and Upper tray [3].
Rotations in both directions are ensured by a elastomeric pad [4] confined by the pot [1] and the piston [2] Displacements in both directions (M Type), one direction (G and T type) or none are ensured by a sliding interphase [SD1] between element [2] and [3]
Uses Bridges (steel and concrete) and any type of civil/Industrial construction
Maximum Vertical Load: (typical pressure >up to 42MPa ULS)
Maximum displacements: unlimited
Maximum rotation: limited to 30 mRad
Advantages High Vertical Loads bearing capacity compared to other bridge bearings such as elastomeric bearings (15 MPa)
Enhanced durability compared to elastomeric bearings (rubber is not fully exposed to environment but confinedinside the pot
